Abstract
An electrified railway power supply system without negative sequence in the whole process and without power supply networks at intervals, can comprise an external power supply system, an input power supply system from external to internal, and an internal power supply system. For external power supply, single-phase power supply is changed to double-phase power supply, and power of a single phase is input to the power supply system within the train via a contactor on a left arm and a right arm of a double-phase pantograph. No neutral section for passing of phase separation is provided in the whole process of operation, and a plurality of sections in the whole process are provided with no power supply network at intervals, and the motor train unit can operate normally without mechanical support for the power supply network.
